“American middle school and high school teachers spend more time educating students than peers in every OECD country except Chile. In addition to classroom time, U.S. teachers are required to be at school for more hours than most of their international peers,” according to a report in the Huffington Post.

The study also noted that despite the long hours, American teachers aren’t well compensated.

“Teacher pay relative to other countries, in absolute terms, is quite competitive in the United States,” said Andreas Schleicher, OECD director of education and skills. “But when you look at this relative to the earnings of other people with college degrees, actually the United States is pretty much at the end of the scale.”

The report concludes:

“The bottom line is that mid- and late-career teachers are not earning what they deserve, nor are they able to gain the salaries that support a middle-class existence.”
